After again repeatedly changing hands, it was finally settled by the renowned William de Burgo, ancestor of the present Marquis of Clanricarde, and remained an appanage to the English crown. At this period, and for some time after, Limerick, was "next in consequence" to Dublin. Richard the First, in the ninth year of his reign, granted it a charter to elect a mayor--an honor which London did not then enjoy, and which Dublin did not receive until a century later; and King John, according to Stanihurst, was "so pleased with the agreeableness of the city, that he caused a very fine castle and bridge to be built there." The castle has endured for above six centuries; in all the "battles, sieges, fortunes," that have since occurred, it has been the object most coveted, perhaps in Ireland, by the contending parties; and it still frowns, a dark mass, upon the waters of the mighty Shannon. The great attraction of Limerick--altho by no means the only one--is, however, its majestic, and beautiful river: "the king of island rivers,"--the "principallest of all in Ireland," writes the quaint old naturalist, Dr. Gerrard Boate. It takes its rise among the mountains of Leitrim--strange to say, the precise spot has not been ascertained--and running for a few miles as an inconsiderable stream, diffuses itself into a spacious lake, called Lough Allyn. Issuing thence it pursues its course for several miles, and forms another small lake, Lough Eike; again spreads itself out into Lough Ree,--a lake fifteen miles in length and four in breadth; and thence proceeds as a broad and rapid river, passing by Athlone; then narrowing again until it reaches Shannon harbor; then widening into far-famed Lough Derg, eighteen miles long and four broad; then progressing until it arrives at Killaloe, where it ceases to be navigable until it waters. Limerick city; from whence it flows in a broad and majestic volume to the ocean for about sixty miles; running a distance of upward of 200 miles from its source to its mouth--between Loop Head and Kerry Head (the space between them being about eight miles), watering ten counties in its progress, and affording facilities for commerce and internal intercourse such as are unparalleled in any other portion of the United Kingdom.
